⭐ Water with Mushroom Bouillon Powder (Best Nut-Free Option)
1 cup water + 1 teaspoon mushroom bouillon powder per 1 cup vegetable brothMushroom bouillon powder contains concentrated umami compounds such as glutamates that mimic the savory complexity of vegetable broth. When dissolved in water, it provides a similar flavor profile and hydration level necessary for proper dough development.
For best results, dissolve the bouillon powder fully in warm water before mixing into the dough to ensure even flavor distribution. Avoid adding excess powder to prevent bitterness.
Compared to vegetable broth, this substitute yields a focaccia with comparable savory notes and moisture, preserving the characteristic tender crumb and subtle flavor complexity.
